Dash Multi-App do not run pages to initiate

Hello @VolGuy,

The function is one step, an additional thing I do is to check if there is a flask.request.

def layout():
    if not flask.request:
        return html.Div()
    # rest of code here

This will keep it from trying to load this layout initially when the app is spinning up, but will cater it like normal when requested.
